IMPROVEMENT IN MACHINERY FOR MAKING'VARIOUS KINDS 0F TWINE AND SMALL COIBD.

Specification forming part of Letters Patent No. 3,220, dated August 17, 1843.

' lowing is a full and exact description thereof.

In the accompanying drawings, Figure isa perspective view of the essential parts of my improved machine. A A is the frame of the twisting-machine, and A- the band-wheel by which motion is given to the spindles and other apparatus concerned in the giving the Y twist to the yarn from which the .twine is to be made. C C are the bobbins which contain the yarn, C C being the frame by which they are sustained. I) is a drum that serves to drive the spindles which run in the box N N, and around the whirls of which passes an endless band b l, that, lapping alternately around the drum and one of the whirls, preserves an equal tension on eachof them. oc c are eyes or fair leaders on the top of the box N N, through which the threads of yarn are to be passed separately preparatory to their being hitched to the hooks of the spindles@ a. From these fair leaders the ends are carried through wires bent spil-ally, as at G, and inserted in the underside of theback rail of the sliding frame F.

Fig. 2 shows the back end of the frame F with its spirally-bent wires G G, this sliding frame constituting a part of what I call the intermediate traveling and laying machine E, which moves back and forth on the ways or railroad M M. The frame F F slides back and forth in grooves l d withinthe checkpieces O O ot' the intermediate machine F., by which arrangement the frame F may be made to occupy either the front or the rear part of said machine.

II is a stake, which is Iirmly fixed in the ground and of which there must be such a number as may be requiredlby the length of twine to be formed. These stakes should be about fifteen feet apart, and they are furnished with wire staples or other similar device, as shown at e e, between which the strands are to drop while the spinning is being effected. lVhere stakes have been heretofore used for a like purpose, they have been made to swing or slide on one side to allow the traveling carriages to pass back and forth,

chine is the constructing of the traveling carriages so that they shall pass freely over the timbers or apparatus to interfere with these stakes, an arrangement 'which gives great facility in the operation ofspinning.

I I is the back-twist traveling carriage for giving the back twist to the twine, said carriage running on the railway M M in the same manner with the carriage vE E. The band-wheel of this carriage is shown at K. The drum or cylinder L carries the bands which actuate the spindlesof this machine, upon which the twine is hooked in the ordinary way. These spindles are not seen in the drawings, being hidden bythe timber f f; but they consist simply of hooked spindles with whirls on them such as are used in the twisting-machine, but usually only one-third as numerous.

lVhen this machine is to be used,- the strands through the fair leaders c @thence to the eyes formed by the spirally-bent Wires on the under side of theslidin g frame F F, the strands being so far keptsingle. "lwo, three, ormore are then hitched on to' the hooked spindles of the back-twist machine I I. The yarns are then severally cut fro'm the bobbins C C of the twisting-1nachine and hitched on to the hooks of the spindles a a.. The machine is then ready to be put into operation. Thein- .termediate traveling maehineF. is at this period near to the back-twisting machine I I. The yarns are to be twisted sufficiently to be ready for the back twist when the machine I I is to be put into operation,the twisting-machine A A being still keptin motion. As the operation goes on the traveling machine will approach the twisting-machine, and when the intermediate machine E is close up to it the sliding frame F F will be made to advance in its grooves to the front of the machine E, so that the doubling and twisting will be effected close up to the t\visting-ma chine.

V.Although the continuing of the twisting operation while the back twist is being given is notin itself new, but is the general praetiee in manufacturing single ropes of large size, it is yet a new feature in th'e twine-machine where a considerable number of strands are simultaneously twisted, and Athe twine and one of the peculiar features of my mastakes, there `not being in said machines any l of yarn are first passed from the bobbins C C manufactured by this process is of a greatly improved quality, the seine or other kinds ot twine requiring a firm texture beingspeci'ally adapted to the, uses for which they are intended.

B is a reel placed on the twisting-machine,

onto which the yarn is to be reeled in skeins by the turning ofthe winch Q.

Having thus fully described the nature of my improved machine for the manufacturing of twine and small cord, what I claim therein as new, and desire to secure by, Letters Patent, is

l. The combining togetherof the twisting,

the intermediate traveling, and the back-twist machines so constructed as that lthey will pass over stationary stakes, as above set forth. 2. The manner of combining the sliding frame with the intermediate traveling frame by which it is allowed to run in grooves from the back tothe front of said frame; and these ,improvements I claim whether the withindescribed machine be made precisely in the form herein represented or in any other producing the same effect by means substantially the same.
